java - 请确认您从正确的目录调用了 Maven

Question

我已经安装了 maven :

C:\Windows\System32>mvn --version
Apache Maven 3.3.3 (7994120775791599e405a7528ec3e0dke21dja06; 2015-04-22T13:57:3
7+02:00)
Maven home: C:\Program Files\Apache Software Foundation\apache-maven-3.3.3
Java version: 1.7.0_51, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.7.0_51\jre
Default locale: de_DE, platform encoding: Cp1252
OS name: "windows 8", version: "6.2", arch: "amd64", family: "windows"

我正在尝试借助 maven 提示生成 Jersey glassfish 项目，但是当我键入以下内容时:

D:\maven>mvn archetype:generate  -DarchetypeGroupId=org.glassfish.jersey.archety
pes -DinteractiveMode=false \ -DarchetypeVersion=2.17

我收到这个错误:

The goal you specified requires a project to execute but there is no POM in this directory (D:\maven). Please verify you invoked Maven from the correct directory. -> [Help 1]

我不明白这个错误:因为我正在尝试生成一个项目，所以这里需要哪个项目？我应该如何创建 pom.xml 文件？我还以为是工程生成的呢。

感谢任何帮助。

编辑 当我输入时没有 \

Answer 1

我现在就去找答案。

所以您的问题的第一部分是字符“\”。参见 this thread

然后是你的第二个问题:据说 The desired archetype does
不存在。 Maven 存储库中不存在此原型(prototype) maven-archetype-quickstart。请引用this link选择您正在寻找的原型(prototype)并将其放入您的命令中。

最后，您的命令必须至少有 2 个参数 -DarchetypeGroupId 和 -DarchetypeArtifactId。例如:

mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes -DarchetypeArtifactId=jersey-quickstart-webapp
